Study to Assess the Impact of the Urine Test Cxbladder Triage Plus on the Number of Cystoscopies Performed on Patients With Invisible Blood in Their Urine.
(CREDIBLE)
What this study is about
This study includes adult patients who see a urologist because of blood in their urine. The amount is so small it can only be seen with a microscope. This is called microhematuria. There can be many reasons for microhematuria. One of them is bladder cancer. While bladder cancer is one of the biggest worries, it is only found in few of these patients.
View original scientific description
This study includes adult patients who see a urologist because of blood in their urine. The amount is so small it can only be seen with a microscope. This is called microhematuria. There can be many reasons for microhematuria. One of them is bladder cancer. While bladder cancer is one of the biggest worries, it is only found in few of these patients. Most microhematuria patients will have a cystoscopy to look inside the bladder. During a cystoscopy, a small camera is inserted into the bladder. This is done through the urethra, the tube that passes urine from the bladder to the outside. In some patients it can cause pain or anxiety. Not all patients have a cystoscopy. Those that don't, usually return for a urine sample within 6 months. This is done to check if there is still blood in their urine. This study is conducted to find out if the use of "Cxbladder Triage Plus" changes the number of cystoscopies in microhematuria patients. Cxbladder Triage Plus is also called "Triage Plus". It is a lab test that was developed to check how likely urothelial carcinoma is present in the bladder. Urothelial carcinoma is by far the most common type of bladder cancer. For the test, the patient voids some urine into a cup. A laboratory then checks the urine of specific genetic material. Abnormalities can be a sign of urothelial carcinoma. The result indicates if the urine is more like most normal urine or more like that of urothelial carcinoma patients. The study is done to find out how Triage Plus changes the number of cystoscopies. Study participants first void urine into a cup. The urine is used for the Triage Plus test. The patients are then assigned to one of two groups. The assignment is random. This means the nobody can influence the assignment. The chance to be assigned to either group is the same. In the test group, the urologist will receive the Triage Plus result and discuss it with the patient. Together they decide whether to do a cystoscopy. In the control group, the urologist will not receive the Triage Plus result. The patient will also not get the result. The urologist and patient will follow standard of care to decide whether to do a cystoscopy. For test group patients, the study gives a recommendation whether to proceed with cystoscopy. It is based on the patient's Triage Plus result. The urologist and patient do not need to follow the recommendation. If the urologist does not follow it, they will complete a survey. The survey has only one question. It is asking for the reasons of the decision. After making their decision, patients will follow the chosen pathway. Data on the performed procedures are collected. The diagnosis will also be documented. Data will be collected for up to about 9 months. To see how Triage Plus changes the number of cystoscopies, these will be counted in each group and then compared.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
